A Robotic System is being developed to automate the crucible packing in the CZ semiconductor wafer production. It requires the delicate manipulation and packing of highly irregular shaped polycrystalline silicon nuggets, into a fragile glass crucible. Here an on-line algorithm is presented to plan the packing. It uses a method called Virtual Trial and Error. The on-line algorithm handles large ...

Case conceptualization is a foundation of cognitive-behavioural therapy (CBT) because it describes and explains clients’ presentations in ways that inform interventions. Yet the evidence base challenges the claimed benefits of case conceptualization. This paper reviews the rationale and evidence base for case conceptualization and outlines a new approach that uses the metaphor of a case concept...

A least-squares spectral finite element method was used to develop an accurate computer code for prediction of solidification from a melt under the influence of an externally applied magnetic field. The computational results indicate significantly different flow-field patterns and thermal fields in the melt and the accrued solid in the cases of full gravity, reduced gravity, and an applied unif...
